a eshrdmw with the invention a t ch -t Fig. 2 is asectional elevation online to of Fig. 1. Fig.3 represents the invention applied to a door.Fig. 4 is a section oflthe kn ob.

This invention relates toseveral devices to a be attached to amoneyrdrawer-or a swinging keeping money. In the bottom of the drawermay be one or more round holes, B, large enough to admit a finger of thehand, asseen in Fig. 2 at B. U is a plate of metal, with flanges turnedup, which plate is secured to the bottom board by small screws throughslots 0 0, so that the plate can slide freely back and forth. Attachedto the rear end of plate 0 is arod, D, which has the other end bent, asat D, so that it passes through the bottom in a slot, E, and is fastenedby a button, E, on the under side of the drawer-bottom. This slot E hasa-return-notch, e, at each end, so that the end D of the rod D can beheld therein, as will be explained. On the other end of plate 0 ispivoted, between the flanges, a serrated plate, 0, the teeth of whichhang over the hole B. On the opposite side of hole B is a plate, 0,similarly serrated, and also pivoted, or so fastened as to allow of aslight motion up and down. Plate 0 has a motion limited to such adistance by stops on the flanges that it cannot pass beyond a fixedline, so that it will always be at an angle much less than ninetydegrees to the plane of the plate 0, to, make it certainto performitsappropriate function, as will be explainedinthe operaoeof th de e- Attah d. to p at 0 is a sp ing-pl te, F, through thebent part, of whichis aguide-rod, G, on which rod is a spiral .spring, Grf, liQ pressesvagainst plate 11, as will bcjexplained.

Thehooked part It en: t l-" lot, in pri g-plat Reedho s F against the recoil of thesprin g G until F. shall be lifted.clear of .h, when the spring forces E toward H, and carries with it theplate Oand serrated plate 0 closeto theOiher serrated plate; and s eepse, ng r. ould at be h mean of i iea l r owe e hi should cautiously shovea stick or anything else in the holelolift theplate F, the discharge ofit over the hooked end it would. dewir him, ndisurpos ne' th dete e.llad discharged its power upon the stick, he should incautiously thrustin his finger to lift the lever, (which will now be described.) thefinger would lift up the teeth of plates 0 U, as seen in Fig. 2, andthus be held.

I is the bolt which holds the drawer locked. It has a shank, J, and abar, J, and another shank, J, opposite to it. These shanks are pivotedto the sides of the drawer at j. The bar and shanks are made heavy, toact as a counterpoise to keep bolt I in its upright position until movedto open the drawer. A bell-wire, d, can be attached to the bar J, orshanks, to be carried to a bell at any convenient distance, so that analarm can be given when there is an attempt to open the drawer. The knobK passes through the front board of the drawer, and has a pin, it,through the inner end, not only to retain it, but, by being extendedabove the edge of the front board, serves as a fastening also. The knobhas a shoulder at it, within a flanged ring or collar of which is coileda spring, 1, which acts against the shoulder is, and keeps the knob Kextended, so that the end of pin it is retained in the notch 70 formedin the front board.

To operate this device, move the connect ing-rod D so that the hookedend D will be in the slot E. The plate G, with serrated plate 0, will bein a free and movable position. The plate F will be held in its properplace by the hook h, and spring G will be strained back. The bar J willrest upon plate F, and, as it were, the trap is set. Should the fingerbe inserted against the plate F, it will be easily lifted up over hookit, when the action of spring G will force F over to H, and carry theserrated plate 0 toward 0, and clasp the finger and prevent itswithdrawal, as shown in Fig. 2. Should any trick be suspected, and,instead of the finger, a stick or rod be put in to lift F, the springingof F and the noise made will induce the person to suppose the dangerover, when, by inserting the finger at B, the serrated plates willreadily yield to the upward motion but an attempt to withdraw the fingerwill close the teeth upon it, and utterly prevent withdrawal thereof.

The notches e e in slot E are for the purpose of retaining the end ofrod D in them, either to fasten the slide 0 one way or the other, as maybe required.

The serrated plates O and C may be applied to a swinging upright door,as shown in Fig. 3, and the hole B may be large enough to admit thewhole hand, when the plates 0 0 must be made in due proportion. Theupper plate 0 will hang vertically by its own weight. The lower one, C,will be keptin place by any arrangement of a spring, 1 2. In both casesthe flange of the inner plate 0 will prevent them from being shoved inbeyond the acute angle described in the former case, so that the hand orfinger will be caught by the teeth.

The fastening to the door can be so attached to a lever or other devicethat it may be unfastened by the hand or finger being thrust through theopening B by the owner of the door or drawer, who is alone familiar withthe means of checking the detective device, as each person employing itwill adopt his own method of checking, one way of which is shown in thebutton E and hook D of the rod D in the outer notch e of the slot E.

What I claim, and desire to secure by Letters Patent, is-

1. The combination of the pivoted serrated plate 0' with the slidingflanged plate 0, when both are applied to a drawer or door,substantially as and for the purpose described.

2. Serrated plate 0, sliding plate 0, and connecting-rod D, working inslot E, combined as shown and described, and arranged to operate inconnection with serrated plate 0, as and for the purpose set forth.

3. The plate F, in combination with the hooked rod H, spring G, andplate G, where by the serrated O is moved over the hole B to operatewith the plate 0, substantially as and for the purpose described.

4. The combination of the plate F, constructed and arranged asdescribed, with the bolt-frame J J J, substantially as and for thepurpose described.

In testimony that I claim the foregoing as my own I aifix my signaturein presence of two witnesses.
